I have updated the model so that it uses default settings that give a good result. If you haven't already installed the model, just download and install Stoned.zip. If you have already installed it then just download the update and extract it to C:\Program Files\Stoned\Stoned.exe, overwriting the existing file.
Full model: http://www.swifttools.com/Stoned.zip (1.35MB)
Update only: http://www.swifttools.com/Update.zip (10KB)
